5093.548.
(a) Notwithstanding Section 5093.547, prior to the designation of the Mokelumne River, its tributaries, or segments thereof as additions to the system, the secretary shall study and submit to the Governor and the Legislature a report that analyzes the suitability or nonsuitability of the proposed designation. The suitability analysis contained in the report shall consider all of the following:(1) The potential effects of the proposed designation on the ability of public agencies and
utilities within the Mokelumne River watershed to meet current and projected future water requirements through the development of new and more reliable water supplies from the Mokelumne River and its tributaries. When considering projected future water requirements, the secretary shall only consider feasible projects to meet foreseeable demands.
(2) Any effects of climate change on river values described in Section 5093.50 and current and projected water supplies.
(3) The following feasibility studies and assessments included within the implementation plan of the Mokelumne Watershed Interregional Sustainability Evaluation, Final Report dated June 12, 2015: 7a, 7b, 7d, and 7f. The inclusion of these studies and assessments in this subdivision shall not be construed as an exemption
from wild and scenic designation.
(4) The instances when the secretary has determined pursuant to Section 5093.55 that a water diversion facility may be constructed on a river or segment of a river that is part of the system.
(5) The instances when the State Water Resources Control Board has approved an application to appropriate water from a river or a segment of a river that is part of the system and what restrictions, if any, were placed on the appropriation of water as a result of the river or segment of a river’s inclusion in the system.
(b) The report shall also include the information required in subdivision (b) of Section 5093.547 and the secretary’s recommendations and proposals with respect to the proposed designation.
(c) The report required for the segments of the Mokelumne River designated for potential addition to the system pursuant to Section 5093.549 shall be submitted to the Legislature and Governor no later than December 31, 2017, and shall include a clear recommendation on the suitability or nonsuitability for addition to the system of each of the designated
segments of the Mokelumne River.
(d) A study undertaken by the secretary pursuant to subdivision (a) shall provide for public input from a broad range of stakeholders.
(e) A report required to be submitted pursuant to subdivision (a) shall be submitted in compliance with Section 9795 of the Government Code.
(f) Until the completion of the study period and the implementation of any recommendation to add segments to the system, or December 31,
2021, whichever occurs first, no dam, reservoir, diversion, or other water impoundment facility may be constructed on any segment designated for study by the secretary as a potential addition to the system unless the secretary determines that the facility is needed to supply domestic water to the residents of the county or counties through which the river and segment flows and the secretary determines that the facility will not adversely affect the free-flowing condition and natural character of the river and segment. This subdivision shall not apply to, and shall not in any way affect, Amador Water Agency’s water rights application 5647X03 pending before the State Water Resources
Control Board.
(g) (1) The secretary shall develop a cost estimate of the study and report required by subdivision (c) and enter into a cost-sharing agreement with the Upper Mokelumne River Watershed Authority. The cost-sharing agreement shall require that the state pay not more than 50 percent of the cost of the study and report required by subdivision (c), with the remaining cost to be paid by the authority. The payment by the authority may consist of appropriated funds or a contribution of services.
(2) Nothing in this section shall preclude any private donations or contributions from interested parties to be used for the purposes of this subdivision.
